ELECTRIC ANNUNCIATOR.

SPECIFICATION forming part of Letters Patent No. 355,791, dated January11, 1887.

Application filed July 31, 1885. Serial No. 173,122. (No model.)

My invention relates to the construction of a simple, efficient, andcheap device for annunciating figures or letters electrically.

The following description fully explains the nature of my said inventionand the man- I ner in which I proceed to construct, apply,

and operate the same, the accompanying drawings being referred to byfigures and letters.

Figure l'represents a side elevation of the 2o apparatus, showing onebracket and magnetspool attached, the shield dropped, and dotted linesshowing the shield up and ready to drop. Fig. 2 represents a frontelevation of the same, showing the shield up, the brackets andmagnet-spool attached, and the armature with escutcheon-pins andstop-pin and one fiat spring. Fig. 3 is a perspective view of theapparatus ready for use. Fig, 4 is a plan'view of the armature with theflat springs attached, and 50 showing the holes for the escntcheon-pinsand the stoppin. Fig. 5 is an edge view of the same. Figs. 6 and 7 aretwo views of the brackets. Figs. 8 and 9 are two views of the shield.

The side pieces of the magnetspool d, which I call brackets 12, are castwith the spool and form one piece, and are attached byscrewsi to a caseor frame, is, Fig. 1. The shield a, made of tin or sheet-brass orcopper, is in the form of a square plate, with an arm on each sideprojecting downward and having the ends bent ontward at a right angle,and in the lower end of each arm there is a hole for attaching it by apin, j, to the] brackets or sides of the magnet, Figs. 1, 3, 8, 9.

The construction and actionof my armature c is peculiar and simple. Itisplaced between the shield and the magnet, and is made of flat ironoblong in form. At one end is a hole for escutcheonpin 9, for holdingand guiding the armature, which is attached to one of themagnet-brackets, and passes loosely through the armature and allows itfree movement at the same time as close as possible to the mag net. Atthe other end of the armature escutcheon-pin 9*, also attached to one ofthe magnet-brackets,passes through the armature, and, being a littlelonger than pin 9, permits the armature to come up higher at the end,where the stop-pin h is attached to it. Near the center of the armature,on the under side, there is attached a thin sheet of brass or othernon-magnetic metal, cut out in the center to one end and forming twoflat springs, e e, Figs. 4 5. In front of the annunciator, in a frame 65 or case, is a sheet of glass or a slit or space, f, to expose thefigure announced.

The peculiar construction of the magnetspool d, which is cast with thesides or brackets, b in one piece, together with the novel con structionof the armature, enables me to utilize the full force of the magnet, andto apply the armature in the most advantageous position. The armature isheld without pivots or flexible sheet of metal by the escutcheon-pins gg the latter pin allowing greater upward movement of the armature at theend, where the stop-pin h is placed. The stop-pin holds the shield a andallows it to drop, when the flat springs e e throw back the armature themoment the current ceases. As in many other electric annuciators, theshield drops by gravity, and the armature, with its stop-pin holding theshield in position out of sight, is attracted to the magnet and allowsthe shield to drop in sight.

The shield is constructed so as to approach as close as possible theglass or clear space f in the case or frame to expose the figureannounced, and at the same time not to be shaded c or obscured by anyother object; At the moment contact is made the armature allows thshield to drop. Having thus fully described my invention, what I claim,and desire to secure by Letters Patent, is.-

An electric annunciatbrconsisting of the magnet d and bracket 12, castin one piece,

and provided with the escutcheon-pins g g, In witness whereof I havehereunto set my the armature c, placed over pins 9 9*, having hand andseal. the non-magnetic springs 6 between it and the magnet, and providedwith the pin h on PAUL SEILER.
